Fill sand quantity with compaction

Compacted fills need more loose material than the finished geometric volume.

This page includes a 15% starting compaction allowance for planning.

  • Default layer: 200 mm.
  • Compaction allowance: 15%.
  • Useful for plinth, trench, and utility fill.

How Is Sand Weight Calculated?

Sand weight is calculated by first converting the measured area or entered volume into cubic metres. Then the calculator adjusts for sand bulking, compaction, moisture, wastage, and delivery units such as tonnes, bags, and vehicle loads.

Step 1 — Calculate Sand Volume

From dimensions: Volume (m³) = Length × Width × Depth

Depth in mm: Depth (m) = Depth (mm) ÷ 1000

Depth in cm: Depth (m) = Depth (cm) ÷ 100

Depth in inches: Depth (m) = Depth (in) × 0.0254

Depth in feet: Depth (m) = Depth (ft) × 0.3048

From direct volume: ft³ ÷ 35.315 = m³

From direct volume: yd³ × 0.7646 = m³

From direct volume: litres ÷ 1000 = m³

Volume is the space that sand has to fill. If dimensions are entered, all dimensions are first converted to metres. If direct volume is entered, the calculator converts that volume into cubic metres.

Step 2 — Apply Bulking Correction

True Dry Volume = Measured Damp Volume ÷ (1 + Bulking Factor)

Example: If bulking is 30%, use factor 0.30

Bulking applies only when damp sand is measured by volume. Damp fine sand can occupy 20–40% more volume without adding the same proportion of dry sand. If sand was measured in a damp state, the calculator reduces the measured volume to its true dry-volume equivalent.

Step 3 — Apply Compaction Factor

Loose Volume Required = Dry Volume × (1 + Compaction % ÷ 100)

If the sand layer will be compacted after placing, extra loose sand is required. This is common for bedding sand, plinth filling, trench filling, and sub-base preparation.

Step 4 — Convert Volume to Dry Weight

Dry Weight (kg) = Loose Volume (m³) × Bulk Density (kg/m³)

Bulk density is the weight of sand per cubic metre, including air gaps between grains. It is not the same as particle density or specific gravity.

Step 5 — Apply Moisture Factor

Adjusted Weight = Dry Weight × Moisture Factor

Dry sand factor = 1.00

Damp sand factor = usually 1.08 to 1.15

Wet sand factor = usually 1.20 to 1.30

Damp or wet sand weighs more than dry sand for the same dry volume. If the supplier delivers sand by weight, moisture can reduce the actual dry sand volume received per tonne.

Step 6 — Add Wastage

Wastage Allowance = Adjusted Weight × (Wastage % ÷ 100)

Order Quantity = Adjusted Weight + Wastage Allowance

Wastage covers handling loss, unloading loss, spreading variation, wind loss for fine sand, and material left on the vehicle or site surface.

Step 7 — Convert to Delivery Units

Tonnes = Order Quantity (kg) ÷ 1000

Bags = Order Quantity (kg) ÷ Bag Size (kg), rounded up

Loads = Order Quantity (kg) ÷ Vehicle Capacity (kg), rounded up

Cost = Tonnes × Price per Tonne

Final order quantity is converted into practical delivery units so users can discuss the result with suppliers in tonnes, bags, or vehicle loads.

Width5 mWidth of area to be filled or covered

Wastage factor5%Allows for handling, unloading, and spreading loss

Step 1 — Calculate Sand Volume

First, the calculator converts the entered dimensions or direct volume into cubic metres. Cubic metres are used because sand bulk density is normally given in kg/m³.

CalculationFormula / SubstitutionResult
Convert length10 m converted to metres10.000 m
Convert width5 m converted to metres5.000 m
Convert depth200 mm converted to metres0.200 m
Measured volume10.000 × 5.000 × 0.20010.000

Step 2 — Apply Bulking Correction

Bulking correction is used only when damp sand is measured by volume. Damp sand may appear to occupy more volume because moisture pushes fine sand particles apart. The calculator converts that measured damp volume into true dry-equivalent volume.

CalculationFormula / SubstitutionResult
True dry volumeBulking correction not applied10.000

Step 3 — Apply Compaction Factor

If sand will be compacted after placing, extra loose volume is needed. The compaction factor estimates the additional loose sand required to achieve the final compacted layer.

CalculationFormula / SubstitutionResult
Loose volume required10.000 × (1 + 15 ÷ 100)11.500

Step 4 — Convert Volume to Dry Weight

Dry weight is calculated by multiplying loose sand volume by bulk density. Bulk density represents the weight of sand per cubic metre, including air voids between grains.

CalculationFormula / SubstitutionResult
Dry weight11.500 × 1,65018,975 kg
Dry weight in tonnes18,975 ÷ 100018.98 tonnes

Step 5 — Apply Moisture Factor

Moisture increases the measured weight of sand. This step adjusts the dry weight based on the selected moisture condition.

CalculationFormula / SubstitutionResult
Moisture adjusted weight18,975 × 1.0018,975 kg
Adjusted weight in tonnes18,975 ÷ 100018.98 tonnes

Step 6 — Add Wastage

Wastage is added after moisture adjustment because the order quantity should include expected site handling and placement losses.

CalculationFormula / SubstitutionResult
Wastage allowance18,975 × (5 ÷ 100)949 kg
Order quantity18,975 + 94919,924 kg

Step 7 — Convert to Delivery Units

Finally, the order quantity is converted into tonnes, bags, vehicle loads, and cost so it can be used for actual procurement.

CalculationFormula / SubstitutionResult
Tonnes19,924 ÷ 100019.92 tonnes
Vehicle loads19,924 ÷ 5,0003.98 loads → plan 4 load(s)

Therefore, the required sand order quantity is 19,924 kg, or 19.92 tonnes, after bulking correction, compaction, moisture adjustment, and wastage.

Calculator Limitations & Assumptions

  • Bulk density values are typical ranges, not quarry-specific. Local sand may differ by 5-10% because of mineral composition, grading, and particle shape. For critical or large projects, obtain a supplier-tested bulk density.
  • The bulking correction is approximate. Actual bulking depends on grain-size distribution and exact moisture content, both of which vary by source. Treat the correction as guidance rather than a precision site test.
  • Dimension mode assumes a rectangular length x width x depth volume. Divide L-shaped, curved, triangular, or irregular areas into simple sections, add their volumes, and use Direct Volume mode.
  • This calculator estimates order quantity and does not specify the correct sand for structural work. Concrete, mortar, plaster, and screed have different grading requirements. Refer to standards such as IS 456, ACI 211, BS 8500, or AS 3600 for design requirements.
  • Unwashed sea sand contains chloride salts that can corrode reinforcing steel and cause masonry efflorescence. Never use unwashed sea sand in reinforced concrete or near metal fixings. The sea-sand option is intended only for properly washed and approved material.
  • Cost is calculated only from the entered price per tonne. Delivery, GST or VAT, taxes, loading charges, minimum-order fees, and other supplier surcharges are not included.

Disclaimer: This calculator provides approximate results for planning and estimation purposes only. Actual requirements may vary based on site conditions, materials, workmanship, and local building regulations. Always consult a qualified engineer, architect, or construction professional before making final decisions.

FAQ

Loose fill sand occupies more volume than the same sand after compaction. Ordering only the finished geometric volume under-supplies the job — this page defaults to a 15% compaction allowance, typical for roller- or plate-compacted fill.
Hand-tamped bedding sand typically needs 8-12% extra; plate-compacted paver base needs 12-18%; heavy roller-compacted fill or foundation sub-base needs 15-20%. Adjust the Compaction field to match your application.
